Has anyone noticed their battery skipping percents after the Android 4.3 update?
When my battery is fully charged it goes from 100% to 98% just from texting, but then it will go down percent by percent after 98. Still holds a charge as it did before the update, but I'm stumped as to why it skips 99%?

Yes..my case is even worse after 4.3 update
it directly goes from 99 to 93 in a matter of moments from unplugging
I am thinking this problem is due to the OTA update?
anyone who flashed the 4.3 RUU has the same problem?
Have you guys tried recalibrating the battery ? Basically you give it a full charge and delete /data/system/batterystats.bin and let it die completely and do the whole battery 0%-100% and back a couple of times
I have the same Problem with 4.3 Android. Battery goes from 100% to 92 % in 1 Minute ? On 4.22 has never this Problems.

I have the same thing.
Although it doesn't happen always.
I'm not sure but I think that it's a calibration problem. I have the feeling that when it says 100% it's not really 100%.
I'm saying this because if I leave the phone to charge for more time then sometimes I don't get the problem.
It's been reported a few times that you need to keep the phone charging for at least another 30min after the LED turns green (or says 100%).

This might have been answered somewhere, but i couldn't find.
My kaiser takes an hour atleast to get to 67% battery level on the power adaptor and as soon as it reaches that level it takes just 5 min to get to 100%. This is very strange. I performed a Radio upgrade to 1.70.19.09 a day before. But this is strange?
The battery status app starts with whopping +600mA of charging current on a 0% charge and drops to 100mA at 50% charged and to +53mA when it is around 67% and then in some time it says 100% with a charging current of +53mA.

Have you tried changing the radio back? To see if that affects anything?
Is your battery life normal? Does the same happen if you let the battery discharge once and charge it again? Changing the radio could have reset the battery meter calibration and it's just finding its way again.

Do you mean to say that i should give a few recharge cycles( a week may be) and this should be resolved?
Run the battery down completely once until the device turns off, that will also allow you to see if you have normal battery life, then recharge fully. Once is enough.

Doesnt work. I completely discharged my kaiser such that it switched off automatically. Recharged to 67% and then shortly 100%. i dont see 70-80-90% charges.
Once it switches off, remove the battery, wait 10 seconds, put it back in, turn on again. If the phone still says low batt and turns off again then your battery is really empty. If not the calibration is really off, run down again until it's really empty, then recharge without interruption until you get the green LED.
You didn't say if your battery life was normal.
same problem here
I have experienced the same issue. Battery is less than 60% and suddenly it reaches 100% (in a couple of minutes). My battery life seems actually very short to me but I must say I started using HSDPA the last week (my carrier finally offered it) and off course my battery lasts much less than before, so it could be just an impression. I flashed hyperdragon III Blackstone (nov 1st) last weekend and the radio is 1.65.24.36.
Just to give you an example, this morning I was listening to streaming radio over HSDPA and battery dropped from 100% to 40% in 50 minutes (screen was off all the time)
So I will try to empty my battery completely and charge it again. I´ll report after that.
My battery charge fluctuates, sometimes it goes up from 5% to 35%, sometimes it seems depleted (2%) and if I check in 15 minutes it's 10% and so on.
I'm running CM 7.2 and previously Darky ROM 10.2. Since this started happening I've used a couple of the top-rated battery calibration tools, but to no avail.
Any ideas? Is it a hardware problem? Or a driver problem with the custom ROMs? Or something else?
Try the following If you haven't already.
Charge phone until it says it's full.
Discharge until it turns off. Try to turn it on to make sure it's absolutely flat.
Do this again.
Then charge it periodically so that you keep the percentage between the 20 and 90 approximately, and see if it improves.
Repeat first steps.
Wiping battery stats and similar "calibration" has no effect on neither the percentage shown or battery performance.

Thanks for the advice, I'll try it and see what happens. Any ideas to the cause of all this? Also, would buying a new battery help?
I don't really know the reason why this is happening, Li ion batteries can be somewhat of a black arts.
A new one should fix it anyway, and they're very cheap where I live at least

I passed through Same problem when i had updated my mobile to jelly bean for first time. But after 7-8 days fluctuates is decreased from +/-20% to +/- 2%. And fluctuates are gone after 20 days.
So dont worry, just wait for 20 days.
I have a Galaxy Nexus, not rooted, and it does this all day. 80%, 14%, 78%. All in a matter of minutes.
I'm discharging fully then doing a full charge to see if it changes anything.
My Sensation never did this and the apps I have are the same. In fact I've installed less on the Nexus...
same problem
i also have this same problem, check this thread...

no one gave me the correct cause or solution.i've done everything i can but no luck.if you get any correct cause or solution pls let me know.anyway I am planning to buy a new battery....
NOTE: These tests were done using branded Orange PL firmware as well as UK Global
symptoms:
1. phone is charged by 100% then unplugged after about one hour
2. 100% is kept for the next 6-7 hours
3. during the day battery drops as normal till about 50%
4. once phone is rebooted battery instead of 50% shows 32%
I don't think the latest phones needs battery calibration (or am I wrong)
Sony has screw up the battery measurement
Hope they will soon release an update
Does anyone have similar issue?

Only happened on second or third day that phone was on last 1% for half hour other then that it is accurate to me.
[edit:] no harm done in deleting /data/system/batterystats.bin after full charge, unplug, let phone go to 1% and then fully charge.

I think I need to wait till 1-2% then charge it up to 100% - then we shall see

Deleting battery stats will do nothing. Battery needs to be calibrated by charging full, unplug, turn off, plug back in till full, pop battery about 30 seconds, put battery back in then boot.

Not sure if this is the definitive answer to this, but you should not believe your battery percentage meter, read this to know why

and didyou read my post? I said no harm in that, but he should do full charge.. and suggestion to pop out the battery fails a bit as T has unremovable battery
Can you guys try this and report back on what happens?
1 - charge battery until green light comes on
2 - while still plugged in, turn the screen on to confirm battery is at 100%
3 - with screen still on (and showing battery at 100%), unplug phone
4 - quickly turn the screen off and back on, and see what the battery says
Most of the time when I do the above, it goes from 100% to a random percentage between 95% and 99%, and it happens even after its been changing all night.
Weird

I'm pretty sure that it has to do with the battery maintenance cycle. Your phone is "done" charging, but instead of overcharging the battery, in depletes it until it gets to a set percent (probably 95) and then charges it back to 99 or 100. This helps the battery last longer, and is why sometimes when you pull it off it says some number less than 100. You just happened to catch it somewhere in the middle of a cycle instead of at the top.

I'm familiar with how that works, but normally it will still show 100% and just deplete quicker until it gets to the low 90's. It's possible that they've changed it so that it now changes to the actual charge instantaneously once unplugged, but that would be different compared to how HTC has done it in the past.
That's all moot though if this only happening to me. That's why I was asking other people to test it - if it happens to everyone then it's probably not a 4.3 bug or a defective battery or something. If it's only happening to me, that's something else entirely. Thanks for the idea though, I hadn't thought of it like that.

That has happened to me on stock rooted since the 4.3 install.
I initially charged to 100, unplugged and watched it go to 95 or so, turned off phone and charged it again until green (at least 20 minutes). I then turned it on, and opened up battery calibrator and calibrated it when it hit 100 percent again (usually 2-3 minutes). This worked for me.

Interesting, maybe I'll try that if it gets too annoying. I'm now leaning towards it being just normal behavior. It's weird though - threw me off.
Hello,
I have an unlocked HTC One and I think I have some problems with the battery. For example, in the morning when I unplug it from charging and it's 100%, if I use it for like 5 minutes then the battery will drop by 6-7% and I don't think that's normal.
Then I was not at home today and I had like 19% and I decided to power it off. Then I turned it on after like 10 minutes, I had 7% left. I left it on for 10-15 minutes without using and it dropped to 2%. I turned it off again and then I turned it back on after like 5 minutes and it had 6%.
What is going on? Should I do a clean install of the software? I'm using ViperOne 6.2.1.
Thank you!

might be some app that is draining your battery, to confirm with gsam battery monitor. Maybe a rom/kernel issue or a bad battery....
Alright so I've done what the guy advised here http://forum.xda-developers.com/showthread.php?t=2765655
Apparently it fixed some of the problems but I still fail to understand this thing: so last night I had 73% battery left. I turned off the phone and then turned it back on after 5 minutes, I had 68% battery left. Why is this?
Also, sometimes the battery level shown while the phone is on does not coincide with the battery level shown in Recovery TWRP. Why is that and what can be done about it?
Thank you!
There is no way to know precisely what proportion of total charge is in a battery, it can only be estimated. Temperature, current drain, and many other factors affect the estimate. I think you're expecting too much.
